Alos (Advanced Land Observing Satellite)

gestartet am 24.01.2006 von der JAXA, Japan, platziert in einem 700km hohen polaren Orbit

Hauptfunktion: Daten für Erdfernerkundung, insbesondere Kartierung der Erdoberfläche und Beobachtung von Naturkatastrophen, Umweltschutzschutz

Sensoren:

• Radarinstrument im L-Band (PalSAR), ermöglicht Erfassung der terrestischen Biomasse aus dem All, Bestimmung der globealen Kohlenstoffvorräte
• panchromatisches Instrument für Stereoaufnahmen (PRISM)
• optisches "Advanced Visible an Near Infrared" Radiometer (Typ AVNIR-2)
